BENJAMIN ROBERTS, OF INDIANAPOLIS, INDIANA.

SMOKE-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 371,365, dated October11, 1887.

Ser'al No. 231,363. (No model.)

. my application Serial No. 2l7,773,filed Novembet-2,1886, and in thatSerial No. 230,736, filed March 12, 1887, whereby, instead of theseveral sprinkling devices shown in said applieations, I am enabled touse a single sprinkling device, consisting of arms mounted upon acentral hub and perforated, preferably upon one side, whereby by theforce of the water issuing from said perforations said arms may berevolved, and the water thus thoroughly distributed throughout theentire interior of the condenser, as will be hereinafter moreparticularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is a central vertical section of a smoke-condenser and adjacent parts,when it is arranged in position in connection with a furnace and boiler,on the dotted line 1 1 in Fig. 2; and Fig. 2 is a horizontal sectionalview looking downwardly from the dotted line 2 2 in Fig. 1.

In said drawings, the portions marked A represent a furnace and boiler;13, the breeching or conduit leading from said furnace to the condenser;C, the body or casing of said condenser; D, the water-supply pipe; andE, the revolving hollow-armed spider, which is the feature of my presentinvention. several parts are all either of an ordinary and well-knownconstruction, or are shown and described in my aforementionedapplication for Letters Patent, and,not being features of mypresentinvention, will not be further described herein, exceptincidentallyin describing the invention.

The revolving spider E consists of a number of hollow arms (four areshown) connected to a central hub mounted upon or connected to the innerend of the water supply pipe D. Said arms are preferably formed ofordinary pipe and should be each perforated upon one Said side, so thatthe water issuing therefrom will cause them to revolve in a manner whichwill be readily understood. This, as will also be readily seen,distributes the water very thoroughly over the entire interior space ofthe condenser, and thus accomplishes by this single device what I haveheretofore accomplished by a larger number of devices, and at the sametime in a manner which is not at all expensive as compared with otherconstructions.

By a reference to Fig. 1 of the drawin s it will be seen that thiswater'distributing device is arranged entirely above the opening throughwhich the products of combustion enter the condenser from the breechingor conduit B, and thus the water issuing therefrom is precipitated uponall said products of combustion, and,foreing them d0wn,assists to form avacuum for the continued inflow ofproducts of combustion.

I may and preferably do employ a crossbar, E, which extends across thecondenser directly underneath the revolving spider and the inner end ofthe water-supply pipe as a support, thereby securing greater stabilityto the structure.

The operation is as follows: The products of combustion are drawn fromthe furnace by the fan B and forced into the condenser. They are theresubjected to a thorough wetting from the spray or line streams of waterwhich issue from the revolving spider. The gases are thereby purifiedand the solids are wet and washed down to the bottom of the condenser,whence they run off with the water and are discharged into a sewer orother suitableplacc. Theatmosphcre ofthc neighborhood where the furnacesare located is thus freed from impurities,and all danger of firefromflying sparks is obviated.

Having thus fully described my said invention,what I claim as new, anddesire to secure by Letters Patent, is

1. In a smoke-condenser, a spider consisting of'perforated hollow armsextending out from a central hub which is secured to or mounted upon thewater supply pipe which extends into the condenser.

2. The combination, in asmoke-comlenser,

of a Water-supply pipe, a spider consisting ofhollow arms, and a centralhub mounted and adapted to revolve on said pipe, said arms be- ICO ingperforated upon one side, and thus adapted to be operated by the forceof the water issuing therefrom.

3. The combination of a furnace, a smoke- 5 condenser, abreeching oroonduitleading from said furnace to said condenser, a water-supply pipeentering said condenser, and a series of perforated pipes connected withsaid water'- supply pipe and located in said condenser IO above theopening therein which communicates with the breeching or conduit,substantially as shown and described.

4:. The combination of a furnace, a smokecondenser, a breeching orconduit leading from 15 said furnace to said condenser, a water supply
